At least one subject might be off-limits when it comes to Jude Law. The star was on “Regis & Kelly” Friday morning, promoting his stint in the Broadway production of “Hamlet” — but one very obvious topic didn’t come up. He was never asked him about his daughter, Sophia,who was just born to model Samantha Burke. Our source said, “He has banned interviewers from asking about it before agreeing to sit with them.” Law’s rep called the claim “ridiculous” and said, “No subjects are banned.”
